Q: I am coming to Barcelona on 21 January for a week. I want to do a day´s walking in the mountains at Montserrat. Please can you tell me what temperature/weather to expect.

A: The weather in Montserrat during the winter months is generally dry but the actual weather conditions depend greatly on whether the sun is out on the day you visit or not or whether it is windy or not. As with walking in any mountain range the weather is much cooler and can change quickly and you should be prepared for this by taking along the appropriate warm clothing and a light water waterproof should you need to use it. If the sun is out it can be very pleasant and you can walk around with just warm clothing. The sun takes out the cold chill out of the air, although it will still be very fresh in Montserrat during the Winter months. If it is overcast then expect it to be cold and you would need to wrap up warm and have extra layers. If it is sunny you can get away with warm winter clothes with a back up of an extra thermal layer like a fleece packed to keep you warm should the sun go in.  The weather gets very much colder around 4 pm onwards as the sun has lost most of its strength at this time. You would be best making sure that if you go for a walk in the Montserrat mountains that you aim to be back before 4 pm to ensure you don´t get caught out with the the very much colder weather once the sun goes in.  During deep Winter months it has been know to snow in Montserrat. The weather and temperatures all really depends on what the weather is like on the day. It can range from pleasant and warm on a sunny day to bitterly cold on a windy and overcast day so be prepared for both extremes.
